iText Image Resize

Question

I have a watermark that I would like to put into my pdf. The watermark is a .bmp image, and is 2290 x 3026. I am having a lot of trouble trying to resize this picture to fit the page, does anyone have any suggestions?

Document document = new Document();  PdfWriter.getInstance(document, new FileOutputStream("result.pdf"));  document.open();  document.add(new Paragraph("hello"));  document.close();  PdfReader reader = new PdfReader("result.pdf");  int number_of_pages = reader.getNumberOfPages();  PdfStamper pdfStamper = new PdfStamper(reader, new FileOutputStream("result_watermark.pdf"));  // Get the PdfContentByte type by pdfStamper.  Image watermark_image = Image.getInstance("abstract(0307).bmp");  int i = 0;  watermark_image.setAbsolutePosition(0, 0); watermark_image.scaleToFit(826, 1100); System.out.println(watermark_image.getScaledWidth()); System.out.println(watermark_image.getScaledHeight());  PdfContentByte add_watermark;  while (i < number_of_pages) {      i++;      add_watermark = pdfStamper.getUnderContent(i);      add_watermark.addImage(watermark_image);  }  pdfStamper.close(); 

Here is the output for the getScaled() methods.

826.0 - Width 1091.4742 - Height 

I would share the picture of the pdf with you guys but unfortunately I can't.

Should I try using a .jpg instead? I don't really know how well iText handles different image extensions.

Answer 1

I do it like that:

//if you would have a chapter indentation int indentation = 0; //whatever Image image = coolPic;  float scaler = ((document.getPageSize().getWidth() - document.leftMargin()                - document.rightMargin() - indentation) / image.getWidth()) * 100;  image.scalePercent(scaler);
